Endless Sky

Explore other star systems. Earn money by trading, carrying passengers, or completing missions. Use your earnings to buy a better ship or to upgrade the weapons and engines on your current one. Blow up pirates. Take sides in a civil war. Or leave human space behind and hope to find some friendly aliens whose culture is more civilized than your own...

Endless Sky is a sandbox-style space exploration game similar to Elite, Escape Velocity, or Star Control. You start out as the captain of a tiny space ship and can choose what to do from there. The game includes a major plot line and many minor missions, but you can choose whether you want to play through the plot or strike out on your own as a merchant or bounty hunter or explorer.

See the player's manual for more information, or the home page for screenshots and the occasional blog post.

Installing the game

Official releases of Endless Sky are available on Steam and as direct downloads from GitHub. A PPA is available for Ubuntu and for Debian. Other package managers may also include the game, though the specific version provided may not be up-to-date.

System Requirements

Endless Sky has very minimal system requirements, meaning most systems should be able to run the game. The most restrictive requirement is likely that your device must support at least OpenGL 3.

RAM 350 MB 750 MB
Graphics OpenGL 3.0 OpenGL 3.3
Storage Free 65 MB 170 MB

Building from source

While most development is done on Linux using the SCons build tool to compile the project, IDE-specific files are provided for XCode and Code::Blocks to simplify the installation on Mac OS and Windows. It is possible to use other IDEs or build systems to compile the game, but support is not provided. For full installation instructions, consult the Build Instructions wiki page.


As a free and open source game, Endless Sky is the product of many peoples' work. Contributions of artwork, storylines, and other writing are most in-demand, while there is a loosely defined development roadmap. Those who wish to contribute are encouraged to review the wiki, and to post in the discussion forum.
